รบกวนพี่ๆทุกท่านที่รู้เรื่อง mail หน่อยครับคือผมมีคำถามอยากทราบเกียวกับการ set ค่านิดหน่อย

<?php

//error_reporting(E_ALL);
error_reporting(E_STRICT);

date_default_timezone_set('America/Toronto');

require_once('PHPMailer/class.phpmailer.php');
//include("class.smtp.php"); // optional, gets called from within class.phpmailer.php if not already loaded

$mail             = new PHPMailer();

$body             = file_get_contents('contents.html');
$body             = eregi_replace("[\]",'',$body);

$mail->IsSMTP(); // telling the class to use SMTP
$mail->Host       = "smtp.gmail.com"; // SMTP server
$mail->SMTPDebug  = 2;                     // enables SMTP debug information (for testing)
                                           // 1 = errors and messages
                                           // 2 = messages only
$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->Host       = 'ssl://smtp.gmail.com:465'; // sets the SMTP server
//$mail->Port       = 26;                    // set the SMTP port for the GMAIL server
$mail->Username   = ""; // SMTP account username
$mail->Password   ="";        // SMTP account password <---------------มันมีปัญหาตรงนี้

$mail->SetFrom('', 'First Last');

$mail->AddReplyTo("","First Last");

$mail->Subject    = "PHPMailer Test Subject via smtp, basic with authentication";

$mail->AltBody    = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test

$mail->MsgHTML($body);

$address = "";
$mail->AddAddress($address, "John Doe");

$mail->AddAttachment("PHPMailer/examples/images/phpmailer.gif");      // attachment
$mail->AddAttachment("PHPMailer/examples/images/phpmailer_mini.gif"); // attachment

if(!$mail->Send()) {
  echo "Mailer Error: " . $mail->ErrorInfo;
} else {
  echo "Message sent!";
}
